So….. ever over carburate?

Lots of racers drive their car to the track. Just Mopar Joe has done a video on a 426 Hemi, using an 850 carb, then a 950. The 850 carb made more tq & hp throughout the whole rpm range. The 850 made 645 hp @ 6800 rpm. There are plenty of examples of smaller carbs outperforming bigger carbs. Above is just one. Bigger is not always better.
Did he try a 1050 or an 1150? If not, his comparison was a bad one. As mentioned above, the 850 generally has bigger venturi. The 950s usually only flow about 830 or so.
